Abstract

In a process for purification of wastewater streams containing phenolic impurities wherein the wastewater stream is contacted with an ether extraction solvent for the extractive removal of the phenolic impurities, to form an ether extract phase containing at least a portion of the phenolic impurities and an aqueous raffinate phase depleted in the phenolic impurities, the improvement which comprises effecting the separation of the phases in the presence of a phase separation promoting amount of at least one polyhydric alcohol.
